DUNCAN MACMILLAN, OF BROOKLYN, NEW YORK, ASSIGNOR OF ONE-HALF TO HERMAN D. MYERS, OF CANTON, OHIO.

STBAP-FASTEN ING.

To all whom it may concern:

Be it known that I, DUNCAN MACMILLAN, n citizen of the United States, residing at Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Stra -Fastenings, of which the following is a fulll), clear, and exact description.

This invention relates to strap end fastenin devices, and more particularly to suoli Iastenings as are used on harnesses.

It is my purpose to provide a fastening device which is simple in structure, inexpensive to manufacture, and is easily secured in place.

Among the advantages of this device are,-the desired connection is readily made; a ull in either direction tends to make the astening more secure; it is readily adjusted or detached; it is particularly usefu on breeching tugs on harnesses, to prevent the tail of the horse from catching, and dispenses with all separate guard-plates or shields, which in the past have performed no other function than that of guarding the buckle from the tail.

While I have shown my invention as applied to the support for a breeching tug, it 1s to be understood that the same may be applied as well wherever two strap ends are to )e detachably secured, and while showing the device in the preferred form, changes may be made in detail without departing from the scope of my invention.

In the drawin s-Figure 1 is a View in side elevation o the complete fastening; Fig. 2 is a plan view of the same; Fig. 3 is a View in central longitudinal section through the fastening device; Fig. 4 is a view similar to that shown in Fig. 3, showing a modification thereof.

1 and 2 are the strap ends to be secured together.

3 is a breaching ring. The end 2 is doubled upon itself, as shown, and the loop thus formed holds the cam shield. The cam shield comprises a slightly arched top member 4, side members 5 depending centrally Specification of Letters Patent.

from each side and connected below the shield by a bearing pivot 6.

7 is a locking-stud or tongue extending upwardly through and above the strap end 2.

8 is the flanged portion or base on the stud 7, adapted to be held between the doubled portions of the strap to secure the stud 7 in place. The strap 1 is provided with the usual perforations 9, of a size to pass over the stud 7 10-10 are tuck loops on the strap end 2.

The operation is as follows: The stra 1 is slid under the arched cam shield, t en over the locking-stud 7, until the roper adjustment is made; and then the eng is passed under the tuck loops 10 and the erforation 9 is pressed down over the locking-stud 7, and a pull on both strap ends completes the operation. The strain in use is such that the cam shield 4 always engages the stra 1 and presses it down firmly over the stu 7. As both ends of the cam shield always press tightly against the strap 1, no projections are presented to catch a horses tail, or to catch any object passing.

In Fig. 4 I have shown a Slight modification, in which the under side of the shield 4 is recessed at 11, to allow the stud to project slightly above the surface of the strap end 1.

When it is desired to adjust or disconnect the straps, it is merely necessary to swing back the cam shield, lift the eyelet 9 from the locking-stud 7 by an upward pressure on strap 1, withdraw the end from tuck loops 10, and then pull out or adjust the strap, as desired.

What I claim is- 1.' In a. device of the character described, the combination of a strap, a cam shield thereon, and a locking-stud inde endently mounted on said strap,projecting a ove said stra and directly under one end of said shie d.

2. In a device of the character described, the combination of a strap, a Swingin solid cam shield mounted intermediate its Iength thereon and having a recess on the under side at one end; a lookin -stud projecting above said strap and direct y under one end of said shield and adapted to enter said rccess.

3. In a device of the character described, the combination of a strap, a locking stud projecting upwardly therefrom, and a solid cam shield mounted to swing upon said strap one end passing over said stud, and having a recess on the under side of the 10 shield having a shoulder adapted to engage the said stud.
